Buying at the specialist dealer or in a boutique is recommended, since only there can various nib widths be tested extensively — the matching nib width is decisive for writing pleasure. Important is to bring one's own paper for trial. At least the standard widths F, M and B should be available. Concretely recommended are the boutiques in Bremen and Munich and specialised online suppliers like scription.de for later replacement purchase. Online purchases are price-attractive but carry the risk of a wrong nib width. Some dealers also offer to test pens from other sources comparatively on site.
